QCA988X hw implements a different cycle counter wraparound behaviour when compared to QCA4019. To properly handle different wraparound logic for these chipsets replace already available bool hw_params member, has_shifted_cc_wraparound, with an enum which could be extended to handle different wraparound behaviour. This patch keeps the existing logic functionally same and a prepares cycle counter wraparound handling to extend for other chips.
